Way to loud exhaust This was single 2.5" after y pipe to MeganRacing resonator to Megan Racing muffler. Basically straight piped. Lots of rasp and annoying imo at WOT. Not considerate for neighbors/am commute. Did pop and ruble nicely or downshift and deceleration.

Great swap! How is the vibration level with the E36 M3 motor mounts and poly transmission mounts? I have stock E36 M3 motor mounts and E46 M3 transmission mounts; had to remove the red poly trans mounts because it buzzed like hell in my S52-swapped car. I am interested in hearing about the difference between E36 and E46 motor mounts.

With stock E46M3 mounts the vibration is not bad at all. I had them on the M44 as well. I wouldn't even say there is much of a difference if any. The trans mounts being UUC black are the lowest tier on their solid mounts. They are ok for DD but around 3K there can be noticeable vibration. I would still run them though personally. If I had the means to easy replace the stock rubber bushings as soon as they got soft I would just stay stock rubber all around. Just because it's still a daily.

Great write up! I have been thinking of doing this or just swapping my auto tranny with a 5 speed. How much did the engine swap cost ya?

Thanks. BlueBimma rebuilt the motor from block up. It's basically a 2.8 M50. Bluebimma did most of the swap and it came with the trans and driveshaft. Overall I have about 4-5 in the swap with all the mods listed. Doing a swap can be much cheaper if you're not gonna tear the motor all the way down. I would go for the 5speed swap first. If your driving style is more in town then try tossing in a 410lsd. I don't miss the M44 but I did have to change my driving style. Where I would wind the M44 out to redine I find myself shifting around 4 in the current setup.

I guess I can provide an update on it. It's my daily currently and while not the most comfortable or convenient still makes me smile. So far it's eaten a water pump (shocker) and I was able to source a Geba locally. PS lines started to leak so reservoir and lines were replaced by a local motorsport shop. Work and a project E30 give me almost no time to focus on this thus not much progress to report. Oil filter housing gasket and vanos line and VC gasket also have been replaced. It was leaking quite a bit from the vanos line that it ended up killing a starter. The starter was very gritty with oil residue all over internals. As of now everything mechanically has been taken care of and I enjoy it everyday.

Going to try new exhaust setup hopefully by mid May. SS longtubes -> ypipe -> 2.5" flex pipe -> Magnaflow straight through muffler -> MeganRacing muffler 3" tips The magnaflow should be a little louder while not being as harsh as it was with just a very small resonator. If not then a new combo. I like playing with exhaust setups.

Before exhaust work, brakes will get least all purchased and lined up to do. Will be going vented stock, blank rotors all around, Pentosin DOT4, ECS SS lines, rebuilt calipers using Stoptech Street pads. Will be adequate for street driving. Thanks to Bimmerbum on the brakes.
